Here comes an engaging challenge for poker masters and math geniuses alike - can you compose equations which give 24 by mixing arithmetic signs and brackets with playing cards? At each round of the game you will be given 4 randomly dealt cards, as well as the arithmetic signs of addition, subtraction, multiplication and division, plus a pair of brackets. The cards carry numerical values same as their numbers, and A equals to 1, J equals to 11, Q equals to 12 and K equals to 13. Click and drag all of the cards to the blackboard underneath, then click to choose suitable arithmetic signs at the bottom left corner to compose a formula that gives 24. You may rearrange the positions of the components on the blackboard by dragging them. When you have finished the task, click the Submit button at the bottom right corner to check whether the formula is valid. If your formula is not correct, you need to rearrange the components again in order to proceed. Each round you will be given 60 seconds to complete the formula, as indicated by the timer at the top right corner of the blackboard. When time is up, a possible answer will be shown but you will be deducted 3000 points. Transform your hand into equations through arithmetic tricks!
